MISCELLANEOUS
This term refers to a restriction in blood supply, causing a shortage of oxygen supply to the tissue, and can lead to cell death.
What is ischemia?
Measuring a patient’s cardiothoracic ratio is a method used to determine if a patient has this pathology.
What is cardiomegaly?
These are the large vessels where pulmonary embolisms are often visualized on a CT scan.
What are the pulmonary arteries?
The sustentaculum tali is located on this bone.
What is the calcaneus?
We ask patients to tuck their chin slightly for CT head scans to avoid irradiating this.
What are the patient’s orbits (specifically the lens)?
When performing an AP foot x-ray with the Fuji system, and the resultant S# is 900, this must be done to exposure technique to obtain a more appropriate exposure to the detector.
What is increasing the exposure technique?
This is the term used to describe a fracture that breaks through the skin.
What is an Open or Compound fracture?
This is the phase post-contrast injection whereby the descending aorta and arteries of the abdomen will be best visualized.
What is the arterial phase?
Before a Feeding Tube can be advanced into the stomach, an x-ray is taken to ensure that the tube is in the esophagus and past the location where the trachea bifurcates, which is known as this.
What is the carina?
This aspect of the vertebrae can be cut out to relieve pressure on the spinal cord, giving relief from nerve pain.
What is the lamina?
This change to exposure technique will help increase subject contrast.
What is decreasing the kVp (and would therefore need to increase mAs).
This is one pathology that can cause a white-out appearance on a chest x-ray.
What is pleural effusion/consolidation/mass/pneumonectomy/total lung collapse (atelectasis)?
The delayed phase of a CT Abdo/Pelvis post-contrast injection is used to best visualize this anatomy.
What are the kidneys/urinary tract?
This is the main source of blood flow to the liver, with approximately 75% of blood flow entering the liver through it.
What is the Hepatic Portal Vein?
This is one method of treating a brain aneurysm.
What is endovascular coiling/aneurysm clip/endovascular flow diversion (stent)?
This is the term used to describe the gradual reduction in intensity of the x-ray beam as it passes through matter.
What is attenuation?
Appearing as a fracture of the anterior glenoid rim, this injury occurs due to forceful subluxation or dislocation of the glenohumeral joint.
What is a bony Bankart lesion?
Before a contrast injection, the MRT must consult with a radiologist if a patient’s eGFR is < than this.
What is 30 eGFR?
The calcaneus will most commonly fracture from this mechanism of injury.
What is a fall from height?
This is the specific name of the view that we would perform if unable to obtain an infero-superior axillary shoulder view.
What is the Garth view? (1/2 points for “downshot”)
This is the name for a small, round bone that can sometimes be found in the back of the knee, embedded in the tendon of the lateral head of the gastrocnemius muscle.
What is a fabella?
Which disease requires that pre-operative Flexion/Extension C-Spine x-rays be taken prior to being intubated in the OR.
What is Rheumatoid Arthritis?
This is the phase post-contrast injection whereby the abdominal organs (especially the liver!) will be best visualized in a CT Abdo/Pelvis.
What is the portal-venous phase?
Stress fractures are often difficult to visualize on X-ray until a few weeks after injury, when this structure begins to form around the fracture site.
What is a bony callus?
A prominent external occipital protuberance/inion (a.k.a. occipital spur), can be well visualized on this radiographic view of the skull?
What is the lateral view?
